Doc,
Did you ever get Happy Frog soil tested? If so, how does it compare?
I ask because I didn't get a batch of DBHBB soil cooking soon enough, so I used some Happy Frog I had laying around to transplant some rooted clones into and they did fine for the first few weeks. The last few days, however, the older leaves have started to dry up and die from the edges in, while new leaves are much lighter that before. I suspect an unbalanced pH since the Happy Frog isn't as mineralized as DBHBB, and I haven't been pH'ing because I'm still using DB drenches and foliar sprays... and I'm lazy.
Anyway, I plan to transplant the ladies from small pots to gallon pots of cooked DBHBB and i hope that will remedy the issue. Do you have any other suggestions?
The photo below was taken about a week ago for size reference.
This Flo is showing early signs of the problem. Also from about a week ago.
Danke.
